iTunes frezen when connecting iPhone: synchronisation fails

Hello,

I have a problem when I connect my iPhone or iPad. I start iTunes, connect my iPhone and then iTunes frezes. The status ball on the screen keeps turning and only an forced stop helps. I have tried several presumed solutions, but nothing helps. I've removed or stopped synchronisation options (OS X: Resetting Sync Services - Apple Support) . This is what EtreCheck finds:

Hopefully anyone can help. I know the memory is to low, but I only want to upgrade when my problem is solved.

Thank you!
